Orcs have no magic. Warcries.

I don't think that because Orcs have the ability to reduce the magic power of the casting opponent, it will be impossible to fight against them. Firstly, the Dwarves – as I understand it, runes won't be removed for them, just as reinforcements won't be removed for the Inferno faction. A very good second option is Necromancers built around Darkness. They have достаточно high magic, and Orcs have достаточно low magic, so mass spells will be достаточно effective, since their duration depends only on magic, and 5-6 is already good. The same story, strangely enough, applies to Mages. Their magic power is also достаточно high, which will allow them to use mass light spells at a decent level. (Summoning will, of course, suffer greatly, which is a bigger problem for Mages than for Necromancers). In addition, there are races with very strong armies of their own that don't focus on magic. Agree, a hundred or two Paladins are a problem in any case, even without magic. And Elven Heroes, due to their army's initiative, start casting when the outcome of the battle is already clear... Warlocks will, of course, be the most affected. But all their units are already достаточно strong, and besides, you can use a different hero development tactic – abandon magic (you can, of course, take Light or Darkness, but they are not native to their own guild, so it is not a fact that they will appear), and focus on developing the strength of the units, with attack upgraded to magic speed (mass acceleration) and defense upgraded to stone skin (mass stone skin) + surprise attack. There is also the possibility of taking leadership with a speed aura, and restoration will also be useful for the Dark Elf. The result is – you can fight! So, it's not so fatal after all... Although, I will play as Orcs now, I really liked them in the third game...
